GeoPrac sponsor Nicholson Construction is working on one of the most challenging grouting jobs in the world right now. They are performing grouting in porous limestone formations under the shipping channel in Miami’s Biscayne Bay as part of the Port of Miami Tunnel project. This grouting work was the featured article in the June 2012 issue of Tunnel Boring Magazine (Here is a link to the story in PDF format). They are being called to perform the work both onshore and offshore to depths up to 126 feet below grade, including inclined holes up to 146 feet deep. Environmental regulations are abig consideration, but even that pales in comparison to the logistical challenges of not impacting cruise ship traffic in the port. Make sure you read about this interesting grouting and tunneling project. [Source: Tunnel Business Online. Image: Tunnel Boring Magazine]
